AMD have had great success so far with their HD7970 and HD7950 high end graphics solutions, however the cost of both models has been prohibitive for many people. The reviews today will appeal to a wider audience who have a budget of around £150 or less to spend on a new graphics card. In this particular review we take a look at the VTX3D HD7770 in both single and dual card configurations.

It would be fair to say that VTX3D have yet to earn a high profile reputation in the enthusiast sector, although we reviewed several of their cards in the past and left with mainly positive feelings. For those who have never read one of our VTX3D reviews, they are a part of parent company TUL Corporation … who are also responsible for the PowerColor brand.

VTX3D mainly use AMD reference designs and coolers, aiming for the lowest price point possible. While there is nothing wrong with this, it can make for a very dull reading (and testing).

Sadly, today they are the only company who have adhered to the AMD reference design, changing only the stickers on the card.

AMD are keen to point out that this is the world’s first GPU released at 1GHZ core clock speed. VTX3D have decided to hold the core clocks at 1GHZ, leaving other partners such as Sapphire to enhance their cooling systems and core/memory speeds.

Before you fall asleep, we decided to spice this review up by partnering the VTX3D card with a reference AMD HD7770, for some Crossfire testing.
